FIELD OF THE INVENTION

The present invention relates to certain 2-phenylimidazo[4,5-b]pyridin-7-amine derivates that are useful as inhibitors of mammalian kinase enzyme activity, including ROR1 tyrosine kinase activity. The invention further relates to certain 2-phenylimidazo[4,5-b]pyridin-7-amine derivates for use in therapy, e.g. for the treatment of medical conditions in which the modulation of human kinase enzyme activity is beneficial. Examples of such a condition include various hyperproliferative diseases, e.g. hematological tumors such as chronic lymphocytic leukemia (CLL), acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL) or mantle cell lymphoma, and also solid tumors such as lung, ovarian, breast or pancreatic tumors. Other examples of such a condition include obesity-associated metabolic complications, autoimmune diseases and inflammatory conditions.

BACKGROUND OF THE INVENTION

Chronic lymphocytic leukemia (CLL) originates from B lymphocytes which differ in activation and maturation stage and are derived from antigen experienced B cells with different immunoglobulin heavy chain variable (IgVH) gene mutations (Chiorazzi N et al., N. Engl. J. Med., 2005, 352, 804-15). Patients with mutated IgVH genes have a better prognosis compared to patients with unmutated genes (Damle R N et al., Blood 1999, 94, 1840-7; Hamblin T J et al., Blood, 1999, 94, 1848-54). Global gene expression profiling studies have revealed partly distinguishing but in general overlapping expression profiles in mutated and unmutated leukemic B cells, suggesting a common phenotype (Klein U et al., J. Exp. Med., 2001, 194, 1625-38; Rosenwald A et al., J. Exp. Med., 2001, 194, 1639-47).

Gene expression profiling studies showed a 43.8 fold increase of the orphan receptor tyrosine kinase (RTK) ROR1 in CLL cells (Klein U et al., J. Exp. Med., 2001, 194, 1625-38). ROR1 is a member of the RTK family of orphan receptors related to muscle specific kinase (MUSK) and Trk neurotrophin receptors (Glass D J, et al., Cell, 1996, 85, 513-23; Masiakowski P et al., J. Biol. Chem., 1992, 267, 26181-90; Valenzuela D M et al., Neuron, 1995, 15, 573-84). ROR receptors are cell surface receptors participating in signal transduction, cell-cell interaction, regulation of cell proliferation, differentiation, cell metabolism and survival (Masiakowski P et al., Biol. Chem., 1992, 267, 26181-90; Yoda A et al., J. Recept. Signal Transduct. Res., 2003, 23, 1-15). They are evolutionarily highly conserved between different species e.g. human, mouse, Drosophila, and C. elegans, suggesting important biological functions.

The human ROR1 gene has a coding region of 2814 bp with a predicted 937 amino acids sequence and 105 kDa protein size including an Ig-like domain, cysteine-rich domain, kringle domain, tyrosine kinase domain, and proline-rich domain (Yoda A et al., J. Recept. Signal Transduct. Res., 2003, 23, 1-15). ROR1 is located on chromosomal region 1p31.3 (http://www.ensembl.org), a region where chromosomal aberrations are not frequently seen in hematological malignancies. The human ROR1 is expressed at the gene level in heart, lung, and kidney but less in placenta, pancreas and skeletal muscles (Reddy U R et al., Oncogene, 1996, 13, 1555-9). Importantly, there is an almost complete absence of ROR1 protein expression in normal human adult tissues and organs. ROR1 was originally cloned from a neuroblastoma cell line (Masiakowski P et al., J. Biol. Chem., 1992, 267, 26181-90) and subsequently a shorter form lacking the entire extracellular domain but containing the transmembrane domain was isolated from a fetal brain library. Truncated ROR1 (t-Rorl) gene has been reported in fetal and adult human central nervous system, in human leukemias, lymphoma cell lines, and in a variety of human cancers derived from neuroectoderm (Reddy U R et al., Oncogene, 1996, 13, 1555-9). A shorter transcript from exons 1-7 including a short part of intron 7 has also been described with a predicted length of 393 amino acids and a molecular weight of 44 kDa (Ensembl ID; ENSG00000185483).

Gene profiling and protein expression studies of patients with chronic lymphocytic leukemia (CLL) has revealed increased expression of ROR1, while mature leucocytes from healthy donors do not express this protein (DaneshManesh, A H et al., Int. J. Cancer, 2008, 123, 1190-5). Silencing of ROR1 with siRNA in CLL cells resulted in apoptosis, while siRNA treatment of B cells from normal donors did not (Choudhury, A et al., Brit. J. Haematol., 2010, 151, 327-35).

Acute myeloid leukemic (AML) stem cells (CD34⁺) may potentially account for the resistance for many cytotoxic drugs. In an in vitro assay, a chimeric antibody against ROR1 (UC99961) inhibited in a dose-dependent manner colony formation of ROR1⁺ AML stem cells but not ROR⁻ AML cells and not normal CD34⁺ stem cells. The results suggest that targeting ROR may represent an important component to eradicate malignant stem cells in AML and potentially also other refractory cancer-stem-cell-driven malignancies (Balaian L et al, Blood, ASH Annual Meeting) 2012, Abstract 2560). In acute lymphoblastic leukemia (ALL) ROR1 is up-regulated modulating in a counterbalancing manner with pre-BCR signaling pathways leading to activation of AKT, ERK and MEK. siRNA transfection induced impaired growth of ALL cells and apoptosis (Bicocca V et al, Cancer Cell, 22, 656-667, 2012).

Human breast cancer cells, but not normal breast epithelia cells also express ROR1. The intensity of ROR1 expression was higher in patients with hormone receptor negative tumors as well as in those with a low degree of cell differentiation, i.e. in patients with a poor prognosis. Silencing of ROR1 impaired the growth in vitro of human breast cancer cells and in immune-deficient mice. The results support the notion that ROR1 is of biological and clinical significance in breast cancer and may be a potential target for therapy (Zang S et al, PLoS One, 7(3): e31127, 2012).

In human lung adenocarcinoma cells ROR1 was overexpressed. The ROR1 kinase activity sustained a favorable prosurvival balance between the proliferative PI3K/AKT and apoptotic p38 signaling, partly through ROR1 kinase-dependent src activation as well as kinase-independent sustainment of EGFR/ERBB3 phosphorylation and PI3K activation. ROR1 knock-down effectively inhibited the growth of lung cancer cells in vitro and in vivo irrespective of EGFR status including those cells resistant to the EGFR tyrosine kinase inhibitor gefitinib. These data also indicate an important biological role of ROR1 in lung cancer and a structure for targeted therapy (Yamaguchi et al, Cancer Cell, 21, 348-361, 2012). Unexpectedly CLL cells showed an overexpression of ERBB2 and phosphorylation of src/PI3K, AKT/mTOR/CREB. The ROR1 tyrosine kinase inhibitors described in this work (see below) dephosphorylated ROR1/src/PI3K/AKT/mTOR/CREB which preceded apoptosis of CLL cells (own unpublished observations).

In another study, a number of solid tumor tissues (lung, ovarian, pancreatic) expressed ROR1 but not the normal cell counterpart. ROR1 expression was associated with high-grade histology and activation of AKT and CREB. Silencing of ROR1 using shRNA induced apoptosis of pancreatic and ovarian cancer cell lines and down regulation of the ROR1 protein as well as of activated AKT and CREB (Zhan S et al, American Journal of Pathology, 181:1903-1910, 2012).

Melanoma cells have been shown to express ROR1. ROR1 siRNA induced down regulation of ROR1 both at the mRNA and protein level, which preceded apoptosis. Targeting ROR1 of the melanoma cells by ROR1 directed monoclonal antibodies induced a significant apoptosis not requiring immune cells or complement. The degree of apoptosis induced by the antibodies varied between the cell lines (Hodjat-Farsangi M et al, PLoS One, 8, e61167, 2013). Furthermore, it has recently been shown that ROR1 plays an important role in adipogenesis and glucose homeostasis in 3T3-L1 cells (Sanchez-Solana, B, Laborda, J and Baladron, V, Molecular Endocrinology 26: 110-127, 2012). Hence, manipulating the WNT pathway, e.g. by modulation of ROR1, to alter adipose cellular makeup may constitute an attractive drug-development target to combat obesity-associated metabolic complications (Christodoulides, C, Lagathu, C, Sethi, J K and Vidal-Puig, A, Trends Endocrinol. Metab., 2009 January; 20(1):16-24).

The above described data serve to illustrate the validity of modulating ROR1 activity for treatment of disorders and diseases that include not only chronic lymphocytic leukemia (CLL) but also other hematological malignancies as well as solid tumors and obesity-associated metabolic complications.

Antibody inhibitors of ROR1 have been described in the literature; e.g. PCT Int. Appl. WO2011079902. There are, however, no small molecule inhibitors of ROR1 known in the art. Substituted imidazo[4,5-b]pyridine compounds are well known in the art, e.g. PCT Int. Appl. WO2003045929, WO2004016270, WO2004016611, WO2006066913, WO2006066914, WO2006080821, WO2006125958, WO2007028135, WO2007072017, WO2007083978, WO2008121063, WO2008121064, WO2009001021, WO2009111277, WO2011066211, WO2013116291, Wang, T. et al.

The compounds of formula (I′) and (I″) are positional isomers (regioisomers), which herein below will be represented by a common formula (I)

wherein ring containing Z and W is in either para position (formula (I′)), or in meta position (formula (I″)). Consequently, unless otherwise specified or apparent from the context, any reference to a compound of formula (I) is to be construed as referring equally to both regioisomers (I′) and (I″). In some embodiments, however, the compound is as represented by formula (I′). In some further embodiments, the compound is as represented by formula (I″).

In some embodiments, the compound of formula (I), or the pharmaceutically acceptable salt thereof, may be used in the treatment of a malignant hyperproliferative disorder or in a method for manufacturing a medicament in the treatment of such a disorder or condition.

In some embodiments, the compound of formula (I), as defined herein, or the pharmaceutically acceptable salt thereof, may be used in the treatment of an obesity-associated metabolic complication as well as in a method for manufacturing a medicament in the treatment of such a disorder or condition.

In some embodiments, the compound of formula (I), as defined herein, or the pharmaceutically acceptable salt thereof, may be used in the treatment of an autoimmune disorder as well as in a method for manufacturing a medicament in the treatment of such a disorder or condition.

In some embodiments, the compound of formula (I), as defined herein, or the pharmaceutically acceptable salt thereof, may be used in the treatment of an inflammatory disorder as well as in a method for manufacturing a medicament in the treatment of such a disorder or condition.

The compounds of formula (I) may be prepared by the person of ordinary skill in the art, using conventional methods of chemical synthesis.

The preparation of intermediates and compounds according to the present invention may in particular be illustrated by the following Schemes 1-5.

The compounds of formula (I) may for example be prepared according to the route shown in Scheme 1. Condensation of the 2,3-diaminopyridine 101 with an aldehyde 102 in the presence of an oxidant such as nitrobenzene at 150-160° C. results in the formation of imidazopyridine of formula (I) (Yadagiri, B and Lown, W J, Synth. Communications, 1990, 20(7), 955-963).

Alternatively, 101 and 102 can be transformed into the compound of formula (I) in the presence of air and p-toluenesulfonic acid in DMF at 80° C. (Xiangming, H, et al., ARKIVOC, 2007, xiii, 150-154).

The synthesis of a compound of formula (I) can alternatively be achieved by the sequence shown in Scheme 2. Treatment of the 2,3-diaminopyridine 101 with an appropriate carboxylic acid 103 in the presence of a suitable coupling agent, such as 1-propanephosphonic acid cyclic anhydride or TBTU, gives the intermediate amide 104 which then is heated in acetic acid between 140-160° C. to yield the compound of formula (I).

The requisite 2,3-diaminopyridines 101 can be prepared by the sequence outlined in Scheme 3. Treatment of the 4-chloro-3-nitro-2-aminopyridine 105 with an appropriate amine 106 in iso-propanol at elevated temperature generates the intermediate 107 via an aromatic nucleophilic substitution. Intermediate 107 is then easily reduced to the desired 2,3-diaminopyridine 101 by a suitable reducing agent, such as iron metal, zinc metal or SnCl₂ under acidic conditions.

Compounds of formula (I) may alternatively be prepared in one step starting from the intermediate 107 and performing the reduction and cyclization steps in a one-pot reaction as shown in Scheme 4. Formation of compounds of formula (I) from 107 and aldehyde 102 is then accomplished with sodium dithionite in ethanol and water at 60-70° C. (Yang, D, et al., Synthesis, 2005, 47-56).

An alternative method of preparation of compounds of formula (I) is shown in Scheme 5. This method involves the introduction of the amine 106 in the last step via aromatic nucleophilic substitution of chloride in the imidazo[4,5-b]pyridine intermediate 108 at 120-160° C. in n-BuOH. (Wang, T, et al., Bioorg. Med. Chem. Lett., 2012, 2063-2069). Intermediate 108 may be prepared by the method shown in Scheme 1.

The necessary starting materials for preparation of the compounds of formula (I) are either commercially available, or may be prepared by methods known in the art.

The reactions described below in the experimental section may be carried out to give a compound of the invention in the form of a free base or as an acid addition salt. The term pharmaceutically acceptable salt of a compound refers to a salt that is pharmaceutically acceptable, as defined herein, and that possesses the desired pharmacological activity of the parent compound. A pharmaceutically acceptable acid addition salt may be obtained by dissolving the free base in a suitable organic solvent and treating the solution with an acid, in accordance with conventional procedures for preparation of acid addition salts from free bases.

Examples of addition salts include salts formed with inorganic acids, e.g. hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid; or formed with organic acids, e.g. acetic acid, benzenesulfonic acid, benzoic acid, camphorsulfonic acid, citric acid, ethanesulfonic acid, fumaric acid, glucoheptonic acid, gluconic acid, glutamic acid, glycolic acid, hydroxynaphtoic acid, 2-hydroxyethanesulfonic acid, lactic acid, maleic acid, malic acid, malonic acid, mandelic acid, methanesulfonic acid, muconic acid, 2-naphthalenesulfonic acid, propionic acid, salicylic acid, succinic acid, tartaric acid, p-toluenesulfonic acid, or trimethylacetic acid.

The compounds of formula (I) may possess one or more chiral carbon atoms, and may therefore be obtained in the form of optical isomers, e.g. as a pure enantiomer, or as a mixture of enantiomers (racemate) or as a mixture of diastereomers. The separation of mixtures of optical isomers to obtain pure enantiomers is well known in the art and may, for example, be achieved by fractional crystallization of salts with optically active (chiral) acids or by chromatographic separation on chiral columns.

The chemicals used in the synthetic routes described herein may include, for example, solvents, reagents, catalysts, and protecting group and deprotecting group reagents. Examples of protecting groups are tert-butoxycarbonyl (Boc), benzyl, trityl (triphenylmethyl) and trimethylsilyl. The methods described above may also additionally include steps, either before or after the steps described specifically herein, to add or to remove suitable protecting groups in order to ultimately allow synthesis of the compounds. In addition, various synthetic steps may be performed in an alternate sequence or order to give the desired compounds. Synthetic chemistry transformations and protecting group methodologies are known in the art and include, for example, those described in R. C. Larock, Comprehensive Organic Transformations, VCH Publishers (1989); L. Fieser and M. Fieser, Fieser and Fieser's Reagents for Organic Synthesis, John Wiley and Sons (1994); L. A.

BIOLOGICAL EXAMPLES

Method for Measurement of Cell Toxicity

The CellTiter-Blue® Cell Viability Assay provides a homogeneous, fluorometric method for estimating the number of viable cells present in multi-well plates. The assay uses the indicator dye resazurin to measure the metabolic capacity of cells. Viable cells retain the ability to reduce resazurin into resorufin, which is highly fluorescent. Nonviable cells rapidly lose metabolic capacity and do not reduce the indicator dye, and thus do not generate a fluorescent signal.

Stock solutions (10 or 100 mM in DMSO) of compounds were serially diluted 1:2 in 11 concentrations and 25 nL/well (100 mM stock) or 50 nL/well (10 mM stock) were acoustically dispensed in assay plates with an EDC acoustic dispenser. Final starting concentration in the assay was 20 μM (0.2% DMSO) or 100 μM (0.1% DMSO) for test compounds.

Peripheral blood mononuclear cells (PBMC) from CLL patients or healthy volunteers were seeded in assay plates (384-well black/clear, Greiner #781091) pre-dispensed with compounds, 25 μL/well, and cultured for 24, 48 and 72 h. The cell concentration was 50 000 cells/well for PBMC from CLL patients or healthy volunteers. After 24, 48 and 72 h culture, Celltiter Blue reagent was added (5 μL/well) and the plates were incubated for 2 h. The plates were read in an Envision fluorescence reader (PerkinElmer) with Ex544 nm/Em590 nm. Results were calculated as % cytotoxicity compared to background (cells treated with 0.2% DMSO).

Examples demonstrating effects on cell toxicity in PBMC from CLL patients and healthy volunteers are illustrated in Table 3. Thus, IC₅₀ values for cell toxicity in PBMC from CLL patients as well as healthy volunteers for some compounds of the invention are shown in Table 3.
